Fabulor 1.0.6

Fabulor 1.0.6 is the first stable release of the modern GTK4 IRC client for Windows 11+ x64.

This release promotes the accepted RC12 client and WiX installer payload, with no additional client changes. External testing covered multiple monitors and detached windows; local WinGet tests passed both an in-place upgrade and a subsequent clean installation with working plugins and retained settings.

Highlights

• Native GTK4 interface with themes, background images, accessible menus, spell checking, emoji and flag pickers, and tray integration.
• Per-Monitor-V2 DPI awareness with a Fabulor-owned fractional-scaling patch for GTK 4.22.4. Installed testing includes 250% and 300% scaling and mixed-monitor use.
• Persistent user-list, Ban List and Ignore List layouts, corrected Ban/Exempt/Invite filters, and installed-font browsing.
• Optional C#, Python 3.14.3 and Tcl plugin runtimes, including the corrected Python runtime replacement during upgrades.
• Installed and portable modes, and installed-mode integration for irc:// and ircs://.

Installation

Download FabulorSetup-v1.0.6.exe below. Close Fabulor before upgrading. RC12 users do not need to uninstall first; the installer offers an upgrade and preserves the user profile.

WinGet distribution is being prepared. It is not available until Microsoft accepts the first manifest submission. Microsoft Store packaging is planned separately.

Unsigned installer and SHA-256

This installer is unsigned. Windows SmartScreen may show Windows protected your PC and Unknown publisher. WinGet does not sign the installer or automatically remove that warning.

SHA-256: AB88A58D2196D734945D2CFBC77258A97C8EBE48F00D1ABDE9028FC74B94E65C

The matching hash confirms file integrity, not publisher identity or safety. Download only from this official release and follow the SmartScreen guidance. Do not disable Defender or SmartScreen.

Known follow-up

• Very long transcript nicknames can overlap timestamps depending on the font and indentation. Optional display limits for nicknames and channel names are planned; full IRC identities will be preserved.
• Generated Python bytecode-cache files may remain under the install folder after uninstall. User profile retention is intentional.
• Additional individually documented DPI-scale coverage and dedicated final Repair testing remain follow-up checks; no claim is made that every scale was separately tested.

Build provenance

Installer: 136,279,565 bytes, from successful Windows Installer Build 35840929543, source 5ae6c3f592fa315a51583707e8f95d24dcfcae86. The embedded MSI matches the separately built MSI byte-for-byte. Release preparation adds documentation and distribution automation without changing client or installer build inputs.

Fabulor v1.0.6-rc.12

Fabulor v1.0.6 RC12

RC12 fixes an in-place upgrade from the earlier PMv2 test build that bundled Python 3.14.6. Windows Installer previously skipped the pinned 3.14.3 Python files as older versions, then removed the test build, leaving the Python runtime incomplete. The corrected installer reinstalls the selected pinned Python runtime during this major upgrade.

Installed acceptance passed: upgrading directly from the 3.14.6 test build installed Runtime\Python314\python314.dll version 3.14.3, and Python plugins loaded without Repair. Clean-install behaviour and the other RC11 features are unchanged.

RC11's Per-Monitor-V2 DPI support remains in this candidate. Please continue mixed-monitor and 100%, 125%, 150%, 175%, 200% and 225% scale testing; 250% and 300% have already passed installed testing. Report any rendering, input or geometry regression.

The Windows x64 installer was built and validated from PR #322 commit faf1ad32efe9a3459a8664ffa07dfe71170c48db by Windows Installer Build run 35446383912. The merged main commit fcfc856fe297733f14916167e828a8f55e724cec has the identical source tree. The bundle's embedded MSI matches the separately built MSI byte for byte.

Windows SmartScreen

Fabulor v1.0.6-rc.11

Fabulor v1.0.6 RC11

RC11 enables Per-Monitor-V2 DPI awareness using a narrowly patched GTK 4.22.4 Windows runtime. Fabulor now responds to fractional scale changes when a window moves between monitors or Windows scaling changes, while saved window, pane and nickname widths remain in GTK logical units. No settings migration is required.

This candidate also corrects Ban List availability and display for bans, exempts and invites, and fixes the OS: (NULL) line in About.

Installed testing passed at 250% and 300%, including live scale changes, long nicknames, stable dividers, themes, backgrounds, compact mode, single-line topics, menus, Ban List and Ignore List. Please continue testing at 100%, 125%, 150%, 175%, 200% and 225%, and across mixed-scale monitors. Report any rendering, input or geometry regression; System-DPI awareness remains the documented fallback.

The Windows x64 installer was built and validated from merged commit 49ecf985cc7be36ad72a27ddbf3360a11c111cad by Windows Installer Build run 35428334660. The patched GTK runtime and exact upstream source archive are published only in Fabulor-owned dependency releases. The bundle's embedded MSI matches the separately built MSI byte for byte.

Known Python upgrade issue

An in-place upgrade from an earlier PMv2 test installer containing Python 3.14.6 can leave the bundled Python runtime incomplete. If Fabulor reports a missing Runtime\Python314\python314.dll, close Fabulor, run this RC11 setup again and choose Repair. Clean installations are not affected. A corrected installer is being validated for the next candidate.

Fabulor GTK 4.22.4 Source Mirror

Fabulor-only mirror of the unchanged GNOME GTK 4.22.4 source archive for reproducible RC11 Windows CI. Original source: https://download.gnome.org/sources/gtk/4.22/gtk-4.22.4.tar.xz. Source commit: 7f99ab1a26408b6499a18f353f081e3c0598ea5c. Archive size: 17,006,720 bytes. SHA-256: 51bd9f60c7d23a665a556c7364c21fb2e4e282566b3e7e092455e8f910330893. The archive is byte-for-byte identical to the pinned upstream source; no ZoiteChat project or release is changed.

Fabulor GTK 4.22.4 PMv2 Runtime 3

Fabulor-only patched GTK 4.22.4 runtime for the RC11 PMv2 candidate. The pinned GTK source and all three tracked patches are recorded at source commit 7661b69. The Win32 display conversion patch explicitly includes math.h; native DPI, coordinate, monitor-rectangle and repeated-transition tests pass. Runtime SHA-256: 8f82cae46791aea986057161390a3ce50e81124b08216db7c7c34005e5fb5b00. Native-test archive SHA-256: 42922c3ba45fb977f942e64b55c6231ec5e9a46646468d81f87307bef657c032. This supersedes pmv2.2 without modifying its assets. The ZoiteChat/gvsbuild builder and its releases remain unchanged.

Fabulor v1.0.6-rc.10

Fabulor v1.0.6 RC10

RC10 is a focused Windows UI follow-up to RC9. It includes:

• stable locking of the User List divider at gui_ulist_nick_width after startup, user-list population, server/channel switching, and later window-state or scale allocations;
• correct transcript indentation for long nicknames when text_max_indent permits it, without allowing nickname text to overlap timestamps;
• corrected packaged GTK4 Fontconfig discovery; and
• immediate population of Settings > Preferences > Appearance > Main font > Browse... without first selecting a filter.

Installed acceptance used a full uninstall and clean installation at 250% Windows desktop scale. The User List retained its configured width through server/channel changes, long nicknames remained within the configured transcript indent, and the font chooser displayed installed fonts without a filter selection. Newly installed fonts are available after restarting Fabulor.

RC10 remains System-DPI-aware. Per-Monitor-V2 DPI awareness is not enabled in this release candidate: the experiment produced disproportionate GTK4 scaling at 250% and 300% and is deferred as an RC11 candidate. Close and restart Fabulor after changing Windows desktop scale.

The transcript Show marker line feature is unchanged.

Fabulor GTK 4.22.4 PMv2 Runtime 2

Immutable Fabulor-owned GTK 4.22.4 runtime candidate for RC11 Per-Monitor-V2 validation. This revision adds outward-rounded Win32 monitor/work-area geometry, negative-coordinate coverage, and state-carrying repeated DPI-transition regression tests. The separate tests archive contains the exact native Win32 fractional-scale executable built against this runtime.

Fabulor GTK 4.22.4 PMv2 Runtime 1

Immutable Windows x64 GTK 4.22.4 runtime for Fabulor RC11 Per-Monitor-V2 support. Built from the pinned ZoiteChat/gvsbuild 2.18.1 source revision with Fabulor's reviewed fractional Win32 surface-scale patch and native scale-conversion regression coverage. GLib remains pinned at 2.88.0. This is a Fabulor build dependency, not an application release. Archive SHA-256: 00792b5cc34d7a8da5b16c4dc6e453a6429d966dae7a18a0a7797e82238e2d4b.

Fabulor v1.0.6-rc.9

Fabulor v1.0.6 RC9

RC9 completes the correction and acceptance work following RC8. It includes:

• reliable preservation of the selected Python, Tcl, and .NET plugin runtimes
  during an in-place major upgrade, correcting RC8's known Python-runtime
  upgrade issue;
• retained Fabulor-owned irc:// and ircs:// registrations through upgrades,
  with explicit URI channel targets preserved when connection fallback is used;
• safer installer maintenance that prevents switching between Portable and
  Installed mode or moving an installation through Modify;
• a prominent warning when Portable mode is pointed at a protected Windows
  directory, with no installation attempted there;
• persistent Ban List and Ignore List dimensions that are not replaced by
  automatic content layout;
• correct locking of the user-list divider when gui_ulist_resizable is off;
  and
• removal of accidental channel-tree and user-list drag sources.

Installed acceptance covered an RC8-to-RC9 upgrade, clean installation,
installed-mode modification, portable installation and uninstall. Plugin
runtimes and add-ons loaded correctly, profiles and settings remained in their
expected locations, irc:// and ircs:// dispatch worked as intended, themes
and background-image controls behaved correctly, and no stability or
performance regression was observed.

Fabulor v1.0.6-rc.8

Fabulor v1.0.6 RC8

Warning

Known installer upgrade issue: RC8 may not preserve the bundled Python
runtime correctly during an in-place upgrade, which can prevent Python
add-ons from loading. Clean installations are unaffected. If upgrading to
RC8, uninstall the existing Fabulor installation first and then install RC8.
The correction has been merged and will be included in RC9.

RC8 is a focused GTK4 interface refinement release. It includes:

• a permanent, compact channel Modes popover in the topic bar;
• responsive topic, input, channel-tree, user-list, meter, Preferences,
  Network List, and Channel List layouts;
• a stable 2x3 user-list action footer with side-by-side meters;
• Fill, Fit, and Centre background-image modes with independent dimming;
• persistent Ban List and Ignore List window dimensions; and
• clear empty states for filtered channel lists and channels with no visible
  users.

The installed regression pass covered disconnect/reconnect, restart
persistence, resizing, themes, background images, list dialogs, empty states,
and normal multi-network use. No freezes, crashes, doubled menus, or unusual
lag were observed.

Windows SmartScreen
